QUESTIONS AND VERIFIED
SOLUTIONS 100% PASS
Which of the following structures changes the volume of the lungs?
a. alveoli
b. heart
c. trachea
d. diaphragm
D. diaphragm
What is the respiratory systems main function
transporting oxygen from the atmosphere into the body's cells and moving carbon dioxide from
the body's cells
How many lobes does the right lung have?
3 (superior, middle, inferior)
How many lobes does the left lung have? Why?
2 because of the heart
How does gas exchange occur in the lungs?
diffusion which is passive transport mechanism
,Where is the heart located
mediastinum
Aveoli
sacs of the lungs where oxygen and carbon dioxide are exchanged by diffusion between the air
and the blood
tidal volume
the amount of air breathed in and out of the lungs during a normal breath
Where is breathing controlled?
medulla oblongata of the brain - monitors carbon dioxide levels and blood ph.
cardiovascular system
responsible for the movement of blood around the body. This system allows for the nutrient
distribution and waste removal.
What type of muscle is the heart?
cardiac muscle - inbolunysty mudvlr
What are the upper chambers of the heart called?
, atria
What are the lower chambers of the heart called?
ventricles
Arteries
carry blood away from the heart
Veins
Blood vessels that carry blood back to the heart
Capillaries
single layer of endothelium that form a network that connect arteries to veins in tissues
Pulmonary loop
carries deoxygenated blood from the right ventricle to the lungs and returns oxygenated blood to
the left atrium
Systemic loop
carries oxygenated blood from the left ventricle to the body, returning deoxygenated blood to the
right atrium
